A Brazilian scientist once described the problem in terms most lab managers in Latin America would recognize: by the time the reagents arrive, they have often expired. Stevens Kastrup Rehen, then at the Federal University of Rio de Janeiro and the Scripps Research Institute, told SciDev.Net that delays were severe enough that chemicals were frequently past their date on delivery. The same report quoted a researcher saying a reagent cost at least twice its US price in Brazil and, with luck, took a month to arrive. The shelf life of a vial does not pause while a customs file moves between agencies.
Two decades of reporting, government papers and trade disputes show that this is not a Brazilian quirk. Brazil and Argentina have each spent years learning what an import bottleneck does to a laboratory, and the lessons apply to anyone who buys research materials across a border.
A month’s wait, a doubled price and a six-month hold
That report came with a petition. More than 300 Brazilian researchers were preparing a declaration to the science ministry arguing that customs policy produced mountains of paperwork for a few microliters or a single reagent. They asked for import taxes on scientific equipment to be abolished and for clearance to take no more than 24 hours.
The same reporting service described a case from 2003 that shows how far the delays can run. Donated research equipment worth more than US$200,000 reached Rio de Janeiro and was then held by customs for six months, and the university was charged US$10,000. Rehen said disagreements between government agencies encouraged the delays.
A 2008 guest post on the PLOS blog, written from the researchers’ side, added a survey. Most respondents had to import supplies for their work at least once a month, and they pointed to the national health surveillance agency, ANVISA, as the main source of delay. The author also noted that the rules for telling a reagent used only in a research laboratory apart from one used in clinical trials or hospitals were not clear. That ambiguity matters, because a vial read as a regulated product can end up in a different queue from one read as a bench chemical.
What Brazil fixed and what researchers built around the gap
Brazil did respond. In 2004 the government created an express program called Importa Fácil for scientists certified by the national research council, CNPq. In December 2007 the federal tax authority published Normative Ruling 7999, which sends imports of research material for CNPq-registered scientists through the so-called Green Channel, an automatic clearance route without physical inspection. Revista Pesquisa FAPESP also reported an ANVISA resolution whose Article 6 promised clearance priority and release within 24 hours.
Fixes on paper did not end the workarounds. A later FAPESP report on supply-side constraints quotes a molecular biologist who, during her doctoral work at the University of São Paulo’s São Carlos Institute of Physics, produced reagents in small quantities in the lab because imported ones took so long. A university group in Campinas has since followed a strategy of swapping locally produced reagents in for imported ones, using startups that make enzymes in Brazil. The pattern is the same each time: when the supply line is slow, the lab either improvises or goes looking for a nearer source.
Argentina’s licensing years, and the cost of buying slow
Argentina’s version ran through paperwork of a different kind. From 2012 to 2015 the country required an advance sworn import declaration, known by its Spanish initials DJAI, before almost any import could proceed. A working paper from the National Bureau of Economic Research describes it as a system of non-automatic import licenses in which requests were granted or withheld at the government’s discretion, with no regulation stating the criteria. Comparing outcomes with a no-policy scenario, the authors estimate that the system lowered import quantities by 31.1 percent and raised import prices by 4.0 percent.
The measure drew a formal challenge. In August 2014 a WTO panel report held that Argentina’s import restrictions were inconsistent with its trade commitments, and from December 2015 the country returned to automatic licenses for most products. The DJAI was a general trade policy, not a rule written for laboratories, but anyone who relies on imported supplies is exposed to whatever regime governs imports at the time.
Argentina later moved to ease the specific problem. Reporting from 2020 describes a measure agreed between the science ministry, the tax authority and customs to simplify the import of scientific supplies, so that researchers could skip standard clearance procedures and receive materials directly in their laboratories.
The human cost shows up in a 2024 report in Science on how Argentine researchers cope with budget cuts. Galo Soler Illia, a nanomaterials chemist, said that “buying it new is often too expensive and slow to import,” so he reuses a reagent left over from a previous project, even one five years old. The workaround, he noted, makes the science slower, because purifying the old material can take a week.
Why a delay changes what a vial is worth
These stories share a point that buyers often miss. A reagent that waits in customs is not the same reagent that left the supplier. Time and temperature change it, the label on the box does not, and a lab that receives a delayed or recycled vial has to decide whether to trust it. That is the situation in which paperwork stops being a formality.
The useful question is whether the documentation can be matched to the material in hand. Published certificate of analysis records, of the kind a Costa Rican supplier keeps as downloadable lab reports for its listed products, give a buyer something to check against the lot number on the vial. A report does not prove that a vial survived its trip, but it does give a lab a baseline, and a missing baseline is the first reason to doubt a delayed shipment.
What local stock changes, and what it does not
One response to the import problem is to shorten the line. Peptides Costa Rica says on its own story page that it keeps stock locally and that its model means no customs step for the customer, and it states that it serves buyers only inside Costa Rica. That removes the cross-border leg that Brazilian and Argentine researchers have spent years fighting. It does not remove the need to check the material.
The same company is explicit about its limits. Its FAQ states that its products are supplied for laboratory and research purposes only, that they are not registered with Costa Rica’s Ministerio de Salud as pharmaceutical products, and that it does not provide dosing guidance, protocols or medical advice. A buyer who treats that as a plain statement of scope, and not as a regulatory approval, will read the supply model correctly: it is a logistics choice, and the quality questions remain the buyer’s to ask.
Four questions are worth asking of any supplier, local or foreign, when a delay is possible. How long did this lot sit before it reached you? At what temperature was it stored along the way? Does the report on file belong to this lot number? And what does the supplier do when the answers are unclear? A catalog such as the one at peptidescostarica.net lists compound names and vial sizes, but the answers to those four questions have to come from the documentation and from the people handling the order.
The shelf, the clock and the label
The complaints from two decades ago still read like a checklist of what can go wrong between a supplier and a bench: a doubled price, a month of waiting, a reagent that is already past its date. Brazil built a Green Channel and Argentina rewrote its licensing rules, and researchers in both countries are still reaching for local alternatives. The clock on a perishable reagent runs whether or not the paperwork is moving.
For a lab in any country, the lesson is concrete. Treat transit time as part of the specification, and treat the date on a report as being as important as the number on it.
